Blender Fluid Sim, Realistic Vomit?
You will need to use particles in Fluid mode, perhaps metaballs if you have the ram for it. This will give you the blobby appearance then render with motion Blur. You'll need to duplicate the particle settings and emitter for blur.





Use vector blur but you can only use Blender internal for that. Make a normal object particle duplicate of the metaball cascade, on a separate layer. Apply this vector blur to the metaball layer.





In the compositor use the 2nd render layer to drive the vector blur.



Results with and with out blur, change vector object  scale to suit blur.



You may have to adjust the particle life of the vector object so that you don't get blurring of the floor.
